A few months ago, shortly before my husband Vishnu and I embarked on our first trip to Japan, I woke up one morning, checked my email and felt my heart skip a few beats. A day earlier, I had written to the travel writer Pico Iyer, who has made Japan his home for nearly three decades now, asking if I could interview him during my visit. I had not expected a personal and warmly worded reply from the man himself.
